Potassium pertechnetate

Potassium pertechnetate is a chemical compound of technetium and potassium, with the chemical formula of KTcO4.

Preparation
Potassium pertechnetate can be obtained by the neutralisation of potassium hydroxide and pertechnetic acid:


 * KOH + HTcO4 -> KTcO4 + H2O

Properties
